Also wow, the Forsaken Vaults are a big step up in terms of difficulty. I died more times on the first floor of that dungeon than I did in the rest of the game combined and eburned through my entire stack of potions to boot. This game is definitely more demanding than the original ever was.
Oh, yes, my first death in the game. I've died around 10 times now, but I only though of one single dungeon as "unfair". You'll know which one. Act II main quest.
And yeah, it gets worse. Better start spending those points in defensive skills.
